Four months after surgery, bony union was detected on radiographic
imaging without a radiolucent zone surrounding the implant (Figure 6 C,
D) and was completely achieved 1 year after surgery (Figure 6 E, F). The
patient could walk without support. The passive range of motion of the
left ankle joint was 10°/20° in dorsiflexion/plantar flexion before
surgery and 10°/5° after surgery. The patient’s JSSF-RA and DAS28 scores
improved from 36 and 3.23 before surgery to 66 and 2.81 after surgery,
respectively.
